Our lab provides robust assessments of energy expenditure and body composition including indirect calorimetry, air displacement plethysmography (BOD POD), and segmental bioelectrical impedance analysis (BIA). Measures of vascular function include brachial artery flow-mediated dilation (FMD), pulse wave velocity, pulse wave analysis, and 24-hour ambulatory blood pressure monitoring.

Current studies
Dietary Supplement Use among Persons with Amyotrophic Lateral SclerosisThis study will help researchers understand which dietary supplements are most commonly used by adults with amyotrophic lateral sclerosis (ALS). Results will inform future studies to examine individual dietary supplements, and knowledge gained can help clinicians dialogue with patients about supplement use.

Associations between Malnutrition and Disease Progression in Amyotrophic Lateral Sclerosis (ALS)Using data from the Pooled Resource Open-Access ALS Clinical Trial Database (PRO-ACT), this study will describe associations between nutrition status defined by the Malnutrition Universal Screening Tool and clinical markers of disease progression.
|
Implications of Electrode Placement on Body Composition Assessment by Bioelectrical Impedance Analysis (BIA)This study led by two doctoral student researchers (Dylis Mensah and Sorour Sarihi) will determine best practices for estimating fat-free mass by bioelectrical impedance analysis (BIA).

Recent studies
Modulating Oxidative Stress and Inflammation in Elders (MOXIE) Study
In this randomized, double-blind, placebo-controlled trial funded by the American Heart Association, Drs. Ellis and Crowe-White examined the effects of habitual intake of 100% watermelon juice on various measures of vascular function among post-menopausal women. Single nucleotide polymorphisms related to inter-individual variability in serum lycopene response were also identified.
|
Dietitians Investigating Needs for Nutrition Education among Retirees (DINNER Study)In this mixed methods study funded by the Academy of Nutrition & Dietetics, Drs. Ellis and Jung described effects of the COVID-19 pandemic on eating behaviors and nutritional status of community-dwelling older adults.
